Description
【考案の詳細な説明】 この実用新案は,十字活栓という血液や薬剤の流出を防ぐ機能を持った留置針 に関するものである。[Detailed Description of the Device] This utility model relates to an indwelling needle having a function of preventing the outflow of blood and drugs, which is called a cross stopcock.
従来の留置針は,患者に使用中の血液や薬剤の流出や噴出を防ぐために留置針 の後部にゴムのチュウブなどを用いカンシではさんだり,チュウブを折り曲げた りしていた。しかしながら,透析などのように動脈に使用する場合は血液の噴出 力が非常に強いため,余程の注意を払って行っても流出する事がしばしばである 。 In conventional indwelling needles, a rubber tube or the like is used at the back of the indwelling needle to prevent the blood or drug being used by the patient from flowing out or spouting, and the tube is bent or bent. However, when it is used for arteries such as dialysis, the ejection force of blood is so strong that it often flows out even with due care.
本考案は,この欠点を除くためなされたもので,これを図について説明すれば ,カテーテル(1)のある部分に一方向がゴム膜(2)で遮断されていて他方が 貫通している十字活栓(5)を設ける。 The present invention has been made in order to eliminate this drawback. Explaining this with reference to the drawings, a cross that is cut off by a rubber film (2) in one direction at one part of the catheter (1) and penetrates the other A stopcock (5) is provided.
本考案は,このような構造であるから,動脈に突き刺す場合は,十字活栓をカ テテーテルの通路を遮断するようにゴム膜がある側を向け,内針(3)をそのゴ ム膜を突き抜けさせて一杯に押し込んで固定して使用する。こうした状態で動脈 内に挿入し,留置針から内針を抜いても血液や薬剤はカテーテル内のゴム膜によ り遮断され留置針から噴出したり流出したりしない。 次に,上のようにして血 管内に挿入された留置針を用いて薬剤を注入したり人口透析を行うときは,カテ ーテルの後部のアダプター(4)に薬剤容器や医療用機器を接続した後,十字活 栓を貫通している側とカテーテル内の通路とを合わすようにすれば薬剤や血液は カテーテル内を通り抜けることが出来る。 Since the present invention has such a structure, when piercing an artery, the cross stopcock is directed to the side with the rubber membrane so as to block the passage of the catheter, and the inner needle (3) is pierced through the gum membrane. Let it push it all the way in and fix it. Even if the inner needle is removed from the indwelling needle by inserting it into the artery in this state, blood and drugs are blocked by the rubber membrane inside the catheter and do not squirt or flow out from the indwelling needle. Next, when injecting a drug or performing artificial dialysis using the indwelling needle inserted into the blood vessel as described above, a drug container or medical device was connected to the adapter (4) at the rear of the catheter. After that, if the side that penetrates the cross plug and the passage inside the catheter are aligned, the drug and blood can pass through the catheter.
